The role of the data modeler has become even more critical to the ongoing lifecycle of development and maintenance, especially in this age of digital transformation. Analysts, developers, DBAs, and BI professionals need to develop their skills in analyzing and modeling data. Whether working with new or legacy data, you must define rules for quality, retention, and protection. And you need a good foundation of data and data design concepts before you begin sourcing, preparing, and manipulating data.
In this introductory course, learn how logical and physical data modeling can give you a better understanding of your organization's data, business rules, and information architecture decisions. Examine how data models are critical to your data security, privacy, and compliance posture. And get hands-on with real-world data—analyze it, implement business requirements, develop data models, and forward and reverse-engineer SQL Server databases.
Note: To complete the hands-on requirements, you’ll work with Office 365, Visual Studio, and Azure SQL Database. Free or limited-time trials are available for these products. You will require an Azure subscription. You can sign up for a free Azure trial subscription (a valid credit card is required for verification, but you will not be charged for Azure services). Note that the free trial is not available in all regions. It is possible to complete the course and earn a certificate without completing the hands-on practices.
Module 1: Introducing Data Modeling Understand the business case for data modeling, and get an introduction to normalization, data modeling taxonomy, and model-driven database design.
Module 2: Designing Logical Data Models Learn about identifying entities, attributes, and relationships, and learn about entity relationship diagramming and metadata capture.
Module 3: Designing Physical Data Models Get the details on transforming a logical data model into a physical model, including designing database-specific features and constraints.
Module 4: Leveraging Data Models on Agile and DevOps Projects Explore the process of data modeling on modern development projects, including planning, continuous delivery, test driven development, continuous integration, sprints, versioning, and deliverables.
completed this course, spending 3 hours a week on it and found the course difficulty to be hard.
I've dropped the course in the middle. As it is often with Microsoft courses, the subject is interesting, but poorly explained and without some additional source of knowledge it may be hard to complete the course. Videos are boring, explanations lacks of clarity. I do not recommend and after several similar experiences I think I'll avoid Microsoft's courses in future.
